FIELD: turbomachines.
SUBSTANCE: blade unit of axial turbomachine contains semicircular row of radially passing blades and casing. Each blade comprises a fin and side branches, wherein each branch has an end with a connecting edge connected to the fin and an end radially opposite the fin. Casing is connected to two opposite fin ends of two adjacent branches of two adjacent blades for connection of fins to casing by means of lateral branches of fins. Branches and the casing form a channel passing through the blade. Connecting edges of the branches are aligned and adjoin along the channel, connecting the branches with each other along the fin. Another invention relates to a turbomachine comprising a compressor comprising the above blade unit.
EFFECT: group of inventions improves stiffness of turbomachine blade.
